Definite seconds for Convivio [on Tudor City Place, just above 42nd.]You might also consider Primola, on the east side of 2nd btw 64 & 65. Very good, old-school cuisine, nice space and decidedly comfortable. The only negative of it is their default Rao-vibe: if they don't feel as if they know you or don't care to, then you might as well ask if they need help bussing tables.
